Reaction Steps

To a solution of 4-fluoro-3-nitrobenzoic acid (5 g, 27.0 mmol) in dimethylformamide (100 mL) was added N,O-dimethylhydroxylamine hydrochloride (5.93 g, 60.8 mmol) and triethylamine (17.0 mL, 122 mmol). 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (11.65 g, 60.8 mmol) and hydroxybenzotriazole (9.31 g, 60.8 mmol) were added and the reaction mixture was stirred at room temperature for 3 days. The reaction mixture was concentrated and partitioned between ethyl acetate (150 mL) and brine (150 mL). The organics were concentrated on rotary evaporator and the crude was purified by flash chromatography eluting with 40% ethyl acetate in hexanes to provide the title product. MS (DCI/NH3) m/z 254 (M+H)+.
